Most of iPhone 4 users didn't update to iOS 4.2.1 as it updates baseband and make it not unlockable. So in case you got an iPhone 4 on older 01.59.00 baseband, we have been tipped off about a solution for that. The below steps will guide you to update iPhone 4 to iOS 4.2.1 while preserving the same older baseband 01.59.00 and unlock it.


STEP 1: Right click on Notepad from Start - Programs - Accessories, then choose Run as administrator from the contextual popup menu.

STEP 2: Once notepad opens, select Open from the File menu then navigate to C:\Windows\System32\drivers\etc\ and open the hosts file as shown:

STEP 3: Now add 74.208.10.249 gs.apple.com to end of the file as shown in the screenshot below:

STEP 4: Now, you'll have to restore your iPhone 4 to iOS 4.2.1 by clicking on the iPhone icon on the left sidebar of iTunes then hold left “alt” button (“Shift” button on Windows) on the keyboard and click on “Restore” then release the alt button, Now Select the original iOS 4.2.1 firmware found here.

STEP 5: iTunes should pop-up with some error as error 1013, 1015 or some other error. This indicates that you have done it successfully, hit OK to continue.

STEP 6: Now you iPhone will stuck in Recovery Mode showing the well-known "Connect to iTunes" message. You have to run TinyUmbrella (Windows - Mac) or RecBoot 2.1 for Mac OS X to get out of recovery mode.

You'll now be able to jailbreak your iPhone 4 using Redsn0w 0.9.6 for tethered and Redsn0w 0.9.7 for untethered one then unlock it using Ultrasn0w carrier unlock. [Thanks @AppleBullet for hat tip, via @Ven000m]

The iPhone Dev Team has just released a new version of Redsn0w with one-click tethered iOS 4.2.1 jailbeak boot support. Redsn0w 0.9.6rc7 includes “one-click tethered boot” support for those of you running the tethered 4.2.1 jailbreak.


With Redsn0w 0.9.6rc7, you can use command-line arguments so you can now bypass the screens you’d normally see as you use redsn0w to “Just boot tethered for now” when your device is rebooted.

Here's the update from the official blog:

We've updated redsn0w to include "one-click" support for those of you
running the tethered 4.2.1 jailbreak. Using command-line arguments,
you can now bypass the screens you'd normally see as you use redsn0w
to "Just boot tethered for now".

The available command line arguments are:

-j to ask redsn0w to "Just boot now"
-i to specify your reference IPSW
-o for old-bootrom iPod touch 2G and iPhone 3GS
-b to specify your own boot logo png

For example, to get redsn0w for Mac to do a tethered boot of an iPod touch 4G jailbroken at 4.2.1:

open ~/Desktop/redsn0w.app --args -j -i ~/Desktop/iPod4,1_4.2.1_8C148_Restore.ipsw

This assumes both redsn0w and the IPSW are on your OS X desktop, so
modify as necessary! Included in the zip is an example script file
that you can double click on to launch redsn0w like this (the Windows
example assumes everything is in C:\). (Mac users: please remember to
change the permissions of your custom *.command files to allow
execution.)

This should help ease the pain of the tethered jailbreak until @comex
comes up with a 4.2.1 untether (or for those of you with legit access
to the 4.2b3 IPSW, until the "Jailbreak Monte" untether is out of
beta)!

- PLEASE UPGRADE TO iTunes 10.1 FOR BEST RESULTS
- WINDOWS 7 USERS SHOULD RUN redsn0w IN "XP COMPATIBILITY" MODE
- Make sure you're using a USB 2.0 port

Please note that the iPhone Dev Team is working on untethering iOS 4.2.1 jailbreak so you don't need to connect your iOS device everytime it reboots. They are have released Redsn0w 0.9.7 beta for Mac OS X, you can try the latest release of this beta but you need iOS 4.2 beta 3 hashes and IPSW file.

UPDATE : Here's the full step by step guide to Boot your Tethered Jailbroken iPhone, iPod Touch and iPad (Windows & Mac) Click Here.

Download Redsn0w 0.9.6rc7 for Windows

Download iTunes 10.1 for Windows and Mac OS X

Most of iPhone 3G and iPhone 3GS users updated their baseband to iPad's one which is 06.15.00 to be able to unlock it. It's not possible to restore using stock firmware on iPad's baseband so you can downgrade to baseband 05.13.xx which is unlockable using ultrasn0w and you'll be able also to restore using stock firmware on this baseband.


This method is not official from the iPhone Dev Team. They are still working on an easy-method to downgrade 06.15.00 baseband to lower ones on both iPhone 3G / 3GS. This method works only on iPhone 3G bootloader 5.8. Follow the steps as mentioned on RedmondPie below:

Here’s what you will need:
- Jailbroken iPhone 3G
- Fuzzyband installed via Cydiaafc2add installed via Cydia
- i-FunBox (for Windows) or DiskAid (for Mac)
- Certificate to use with Fuzzyband.

And the step by step procedure is as follows:

STEP 1: Download the required certificate file ICE2-06.15.00.cert from here.

STEP 2: Install Fuzzyband from Cydia and start this app.

STEP 3: Connect your iPhone 3G with computer via USB cable.

STEP 4: Start i-FunBox and click File, then navigate to Applications/Fuzzyband.app, right-click and then select Copy from PC.

STEP 5: Select the ICE2-06.15.00.cert file you downloaded earlier and then copy it to this location:Applications/Fuzzyband.app.

STEP 6: Now simply disconnect your iPhone from your computer and start Fuzzyband app (which you previously installed using Cydia) on your iPhone.

STEP 7: In Fuzzyband, you will now see your current version of Baseband, (which should still be 06.15.00). But now you will have the option to downgrade it to version 05.13.xx.

Once you have downgraded, Go to Settings –> About, and scroll down to check your Baseband which should now read 05.13.xx (which is unlockable via Ultrasn0w). You can now also update or restore any firmware without iTunes throwing errors. 

So, got it? Fell free to leave us a comment with results !

As promised, the iPhone Dev Team has released the necessary jailbreak tools which can untether the latest iOS 4.2.1 jailbreak on iPhone 4, iPod touch 4G, and iPad. Old-generation iOS devices already have untethered jailbreak on iOS 4.2.1.


For those who don't know, Apple has already patched the untethered patch in iOS 4.2.1 update so it becomes tethered jailbreak on new-generation devices mentioned above. Being tethered jailbroken means that once your iPhone is successfully jailbroken, you'll need to connect your iPhone to your computer if you ever need to reboot your iPhone or your iPhone loses battery charge. The updates Redsn0w 0.9.7 brings untethered jailbreak for those devices on iOS 4.2.1.

Below is the full step-by-step guide to jailbreak your iOS device using Redsn0w 0.9.7 and get untethered jailbreak immediately.

STEP 1: First of all, you have to jailbreak your iOS 4.2.1 device using Redsn0w by following the step by step instructions posted here.

STEP 2: Once jailbroken, tap on Cydia and check if your 4.2b3 SHSH blobs saved or not. You should see "SHSH: 4.2b3" in the status as shown in the screenshot below:
STEP 3: Now download Redsn0w 0.9.7b1 from the links given below and connect your iPhone, iPod touch or iPad.

STEP 4: Since this is a beta release, you must have usbmuxd that can be download from here. Now start terminal in python-client directory then type in the following commands:

chmod +x tcprelay.py

./tcprelay.py -t 22:2222

STEP 5: Now start Redsn0w 0.9.7 and point it to the official iOS 4.2.1 .IPSW file.
STEP 6: In the next page, check on Jailbreak Monte which untethers your iOS 4.2.1 jailbreak then point it to iOS 4.2 beta 3 firmware (helpful link).
STEP 7: Final step is to put your iOS device in DFU Mode using Redsn0w instructions on the screen.

Finally, sit back and let Redsn0w go in bunch of steps and you'll finally get untethered jailbreak on your new-generation iOS device.

Please note that this is a beta release, and upcoming versions will bring support for Windows users and will have built-in usbmuxd for easy process.

Download Redsn0w 0.9.7b4 for Mac OS X
Download iOS 4.2.1 for iPhone, iPad and iPod touch
Download iTunes 10.1.1 for Windows / Mac OS X


UPDATE 1: Redsn0w 0.9.7b2 is available for download (link above edited), check here for changelog.

UPDATE 2: Redsn0w 0.9.7b3 now available. This version extends the fix made in beta2 over to the non-GUI programs too (like the daemons that handle media content). So now embedded videos in iTunes work. The same link above.

UPDATE 3: Redsn0w 0.9.7b4 has been released to Untethered Jailbreak Without the Need of ‘usbmuxd’ Process , check full details Click Here. 

In case you have unlocked your iPhone 3GS / 3G by flashing iPad baseband 6.15.00 with ultrasn0w 1.2 on iOS 4.2.1, and have issues while restoring your device, here is Sherif Hashim the guy behind ultrasn0w unlock tool, has posted a simple guide showing how to restore your iPhone 3GS / 3G to avoid iTunes errors.


Note: To restore your iPhone 3GS from 4.2.1 to 4.1, you must have saved SHSH blobs for iOS 4.1.

For PwnageTool users:

A :  If you are on Mac and use PwnageTool: If you used pwnage tool then you will have to create a “new” custom 4.1 or 4.2.1 and say “No” when you are offered the BB update to 6.15.00 since you already have it, then build the custom ipsw and restore to that.

For Redsn0w users:

B : If you use(d) Redsn0w:

B.1: If you are currently on 4.1, then you can restore to official 4.1 again, and when you see error 1015 pop-up, you kick your device out of recovery mode using TinyUmbrella, use redsn0w and don’t check “ipad BB update” because you already have that Here Is How To Restore iPhone 3G And iPhone 3GS While On Baseband 06.15.00 And Having Issues icon smile

B.2: If you are currently on 4.2.1 then you’ll have to restore back to 4.1 (because 4.2.1 will not allow you to kick the phone out of recovery when 1015 occurs due to the silly BB / iOS mismatch check added there) , then do the same steps as CASE-1.

How to go again to iOS 4.2.1:

If you want to go again to 4.2.1 your only way is to use a custom 4.2.1 done by pwnage tool in the same steps mentioned in A .

Try Hashim's methods above to restore you device between 4.2.1 and 4.1, it worth trying. Don't forget to tell us about your experience.

Have you ever wanted to watch a video on your iOS device, but you needed flash? Now you can watch videos on your device using iOSFlashVideo! Neither jailbreak or payments required for this method! Just follow the steps below and you can play your flash videos on your iOS device easily.

The iPhone Dev Team has just released ultrasn0w 1.2 which brings carrier unlock for iPhone 3GS and iPhone 3G on iOS 4.2.1 or iOS 4.1.

From the iPhone Dev Team Blog:

Today we’re pleased to announce our free carrier unlock for iPhone3G/3GS owners with a baseband later than 05.13.04.  The unlock for that baseband exploited the AT+XAPP command, thanks to a crash initially discovered by @sherif_hashim (@Oranav also found this crash).  So what hole are we exploiting today, since Apple closed that AT+XAPP hole?  Well, we’re exploiting the exact same hole!

It turns out that the very first iPad firmware 3.2.2 has baseband version 06.15.00 still vulnerable to AT+XAPP.  The iPad baseband is built for the exact same baseband chip as the iPhone3G/3GS — they’re fully compatible!  Some of us have been running 06.15 for weeks now on our iPhones in preparation for this release.

Since 06.15 is a higher version than 05.14 or 05.15 (where AT+XAPP is gone), anyone stuck at those versions can simply upgrade to 06.15 to unlock again!  Luckily for us, Apple *still* provides the iPad FW 3.2.2 with this vulnerable baseband right from their own servers. (Grab it now, before they take it down!)
We’ve been busy updating both PwnageTool and redsn0w to make the baseband update as seamless as possible.

1. First up is “PwnageTool 4.1.3 Unlock Edition”.  It has a special dialog box which will ask you if you want to update to the iPad baseband.  You must already have the iPad 3.2.2 IPSW on your computer (see the above link)….so just point PwnageTool at it (or let it find it on its own if you’re in “simple” mode).
2. Directly after PwnageTool 4.1.3 is available, the official ultrasn0w repo http://repo666.ultrasn0w.com will be updated with ultrasn0w 1.2, which covers iPhone 4 baseband 01.59.00 and iPhone 3G/3GS basebands 04.26.08, 05.11.07, 05.12.01, 05.13.04 and now 06.15.00.
3. Finally, we’ll release an update to redsn0w today for those without Macs and can’t run PwnageTool.  The new redsn0w will give you the option to update your baseband to 06.15 too.

WARNING — YOU DO THIS AT YOUR OWN RISK!  PLEASE UNDERSTAND THE CONSEQUENCES OF UPDATING TO 06.15.

1. There is no way to come back down from 06.15, and there’s no hiding the baseband version from Apple.  You’ll be voiding your warranty in a very obvious way.
2. If some future baseband comes out with a critical fix, you won’t be able to update to it if it remains down in the 05.xx sequence (then again, you wouldn’t update to it if you wanted to keep your unlock anyway).
3. Starting with FW 4.2.1 if you have 06.15 on your iPhone you won’t ever be able to restore to stock firmware (it will fail).  You’ll need to only restore to custom IPSWs (then again, if you’re unlocker you should already be doing that).

Certainly don’t update to 06.15 if you don’t need to!  Only do this if you need the unlock and you’re stuck on 05.14 or 05.15, and you’re willing to assume the above risks.

This PwnageTool also contains a 4.2.1 bundle for iPhone3G owners…for all else, it’s still only 4.1.  If you have an iPhone3GS with an old bootrom, the new redsn0w will handle 4.2.1 for you (in fact it covers 4.2.1 for all devices, even though some of them are still tethered at 4.2.1 until @comex can work some untethering magic).  iPhone3GS users with old bootroms who want to go to 4.2.1 should not use this PwnageTool!  Update to stock 4.2.1 first, then use the upcoming redsn0w to update your baseband.

Please feel free to use our comments section for questions.  We have some very knowledgeable and helpful moderators:  angiepangie, Confucious, dhlizard, and Frank55!

Simply follow the instructions posted below to unlock your iPhone 3GS / 3G on iOS 4.2.1. / 4.1 on 05.15.04 and 05.14.02 basebands.

How to: Jailbreak iPhone 3GS / 3G on iOS 4.2.1:
STEP 1: Unlocking requires that your iPhone is jailbroken. Follow our updated guide posted here to use PwnageTool to update your baseband so you can unlock, or follow our guide posted here to use reds0w 0.9.6b5 (Windows & Mac OS X) to do the same as PwnageTool to update baseband to 06.15.00.

How to: Unlock iPhone 3GS / 3G on iOS 4.2.1:
STEP 2: Once you jailbreak yoour device, you can now unlock your iPhone on baseband 06.15.00 using Ultrasn0w 1.2 from Cydia. To do so, follow the steps below:

• Press to launch Cydia Installer from your SpringBoard.
• Press to select the Manage tab at the bottom of the screen.
• Press to select the Sources button

• Now touch on Edit and then on Add. You will be prompted to enter the URL of the source. Type http://repo666.ultrasn0w.com and touch on Add Source to add this repository. 

• Once the source has been added press the large Return to Cydia button then select the Done button at the top right of the screen.
• Now select repo666.ultrasn0w.com from the sources list and at last select ultrasn0w from the list of packages as shown below then install this application.

STEP 3: Almost done, now simply reboot your iPhone and you should have a fully unlocked iPhone 3GS on iOS 4.1 or iOS 4.2.1.

Unfortunately, iPhone 4 unlockers have to wait a bit longer before they can use their device on any carrier they like but at least they had promised to start working on that starting from tomorrow.

As most of you know, AirPrint may be the most interesting feature in the newly released iOS 4.2.1 that allows you to print documents and files directly from your iPhone, iPad or iPod touch. But not all devices will be able to enjoy this function, so we will show you how to enable AirPrint on non-supported devices as iPhone 3G and iPod touch 2G.


STEP 1: Download Redsn0w 0.9.6b3 (Windows - Mac OS X).

STEP 2: Download iOS 4.2.1 original firmware from here.

STEP 3: Connect your device into your computer via USB and launch Redsn0w you download in step 1. Click on browse and point it to the original iOS 4.2.1 firmware of your device and wait while it's recognized.
STEP 4: Now you have to check on Enable Multitasking, other items are optional.
STEP 5: Put your iPhone into DFU mode by following the instructions on the screen:

• Hold down the Power button for 5 seconds.
• Without releasing the Power button, also hold Home buttons together for 10 seconds.
• Now release the Power button but keep holding the Home button for 15 seconds.

STEP 6: Once done, your iPhone will be rebooted and you'll get AirPrint on iPhone 3G ad iPod touch 2G.

From now on, when you open a page in Safari, you'll see the Print button by clicking on the share icon at the bottom. With this option, you can set how many copies of documents you want to copy. You have to select the printer (must be one of the 11 supported printers) and hit Print.
In case your printer is not supported by Apple, you can download and install Printopia to enable AirPrint on non-supported printers. [iPhoneItalia]

To be clear infront of you, I have tried the following guide several times until it finally worked thanks to the original Cydia binary and Johnny's Cydia patch. Anyway, you can now patch Cydia on jailbreak iOS 4.2.1 devices with simple steps can be found below.


STEP 1: First of all, you need a jailbroken device running iOS 4.2.1, so you can use our posted here to jailbreak iOS 4.2.1 on iOS devices using Redsn0w.

STEP 2: Download Cydia.patch file for iOS 4.2.1 from here and copy it to /Applications/Cydia.app/Cydia_ by SSH’ing into your iOS device (using the guide posted here to enable SSH on your iOS device).

STEP 3: Now type the following commands in terminal app on Mac OS X by using the original Cydia binary from here:

apt-get update

apt-get install bsdiff

cd/Applications/Cydia.app/

cp Cydia_ Cydia.bak
bspatch Cydia.bak Cydia_ Cydia.patch

chmod +x+s Cydia_

STEP 4: Finally, reboot your device and enjoy Cydia on your device.

If you rely on unlock, it's recommended you stay away from Redsn0w as you will lose your unlock on your iOS device. From now on, you will need to boot using Redsn0w whenever your device is rebooted until comex make iOS 4.2.x jailbreak untethered. So, whenever you want to SSH into your device, you must first run your device in the “jailbroken state” on every reboot by using “Just boot tethered right now” option in Redsn0w. We'll be happy to answer your questions. [via Johnny iPhone]
